Hi All
I'm using LinkedList to maintain a history and the elements are ordered
by their timestamps. Every now and then I would "expunge" the list, that
is to say, iterating through the list and when an element is old enough
all elements after (and including) it will be removed. Currently I'm
removing them one by one.
Is there a way to truncate the list using a single method?
Thanks

Hi Max,
You could try to use AbstractList.subList(...)
<http://docs.oracle.com/javase/6/docs/api/java/util/AbstractList.html#subList%28int,%20int%29>
Quoting from the doc:
For example, the following idiom removes a range of elements from a list:
list.subList(from, to).clear();
